Review this essay correcting expression and grammar errors. When it comes to some subjects, ideas and concepts are much more important than facts. Other disciplines, on the contrary, value facts over ideas. In eventual cases, ideas, concepts, and facts get mixed to produce more knowledge. For example, if you study history it is very important for you to memorize as many facts as you can. Presidents, cities, dates and another facts can enrich your knowledge about world war two more than just having an idea that Germany was defeated. On the other hand, if you study physics it will be of more use to you if you learn the ideas associated with the concept of a black hole. Mathematicians use definitions and formulas(known facts) to get to a new conclusion(idea). In general, it is highly dependent on how much an object of study allows you to apply a creative process when learning it. Since, for example, while studying history it is not enough to just conceptualize things, you better stay with facts. You can, of course, come up with some really fancy explanation why the Roman empire felt but as long as you cannot prove this, everything remains only that, ideas. In the end, when used wisely, ideas, concepts and facts have their own place in the learning process. It is up to the student to know when and how to use each one while studying.
